Example

Let's say you have an existing workflow that, when triggered through webhook, creates a card in Trello, and sends the card details through email.

Let's create a dynamic, or parameterized account for Trello and Gmail.

1. Retrieve service access token and create object.
   Using your account's OAuth server, create an access token for the service \(in this case, Trello\) and insert it in the access\_token field of the following object. This is the standard object to be used for all service actions:

   [ 
     { 
        "auth" : { "access_token" : "9276fb05d973105df631d29894a8b49af8564b85951d121d0ca584a29761d89c" },     
        "actions" : [ "a0" ] 
     } 
   ]

   Here, a0 refers to the Id of the action you want to create a parameterized account for. You can find this Id at the lower-left corner of the action configuration window.

2. Next, retrieve an access token for the Gmail service and add it to the object for Gmail service. Add this object below the Trello object. So, it becomes:

   [ 
       { 
          "auth" : { "access_token" : "9276fb05d973105df631d29894a8b49af8564b85951d121d0ca584a29761d89c" },     
          "actions" : [ "a0" ] 
       },
   
       { 
           "auth" : { "access_token" : "ya94.GltcBIa387LWmFugL3Zi9m23yslgx4xkaIzeUR6ZeHkYD0ZfcBQdLHi2A" }, 
           "actions" : [ "a1" ] 
       } 
   ]

3. Encode object. Once you have created the object, encode it with base64 encoding. You can use this online service to encode the object.

   

4. Append encoded object to webhook URL.

   Once you have encoded the object, you can append it to the webhook URL of the workflow you wish to execute. Add ?authorizations= to your webhook URL, followed by your encoded object.

   For example, if https://runflow.built.io/run/8... is the webhook URL of the workflow, add ?authorizations= followed by the encoded data. Your webhook URL will look something like this: https://runflow.built.io/run/8...?authorizations=IFsgDQogICAgICAgeyANCiAgICAgICAgICJ0b2tlbiIgO…

5. Execute the webhook URL. Now, when you execute the above webhook URL, it will call the workflow and replace the existing accounts with the parameterized accounts.
